The ICS843101I-100 has been characterized with 18pF
parallel resonant crystals. The capacitor values shown in Figure
IDT
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS843101I-100 provides
separate power supplies to isolate any high switching noise
from the outputs to the internal PLL. V
be
plane through vias, and bypass capacitors should be
used for each pin. To achieve optimum jitter performance, power
supply isolation is required. Figure 2 illustrates how
a 10
capacitor should be connected to each V
